Method for solving quadratic equation?
completing the square.. given: x2 +6x+13=74 make into perfect square trinomeil... 1. isolate x terms x2 +6x=61 divide the coeffiecent on x term by 2, square the quotent and add to both sides x2 +6x+9=61+9 factor (x+3)2 =70 take square root of both sides x+3=plus or minus sqr(70) x=-3+sqr(70) x=-3-sqr(70)
